User profile IB: Clinical/practice assistant
In addition to the experience described in user profiles I and IA, the user
(e.g., doctor's assistant, nurse) should have knowledge of pathological
factors which influence measurement quality, as listed below:
•
Cataract-related light scattering of optical media
•
Corneal opacity-related light scattering of optical media
•
Optimization of device settings (e.g. cataract modes) with the aid of the
user manual, to minimize pathological factors that influence measurement
quality
User profile II: Analysis of measured data
The user (e.g. BSc, certified engineer, master, general ophthalmologist)
should have the experience described under user profiles I, IA and 1B. In
addition, he/she should have a sound knowledge of:
•
Accuracy, interpretation and possible sources of error of
measurement data based on Placido disc and Hartmann-Shack
technology
•
Diagnosis of measurement data based on medical devices
•
Standard ophthalmological/optometrical measuring records and
readings, as well as their interpretation, resulting diagnoses,
prescription of visual aids or therapeutic treatment, etc.
•
Corneal pathologies associated with corneal topography
•
The applied therapy method in the interpretation of readings for
therapy planning and implementation
•
Consequences of incorrect or inaccurate readings and careful
validation of readings (quality evaluation, multiple readings, test of
consistency with other diagnostic results)
A typical patient work flow scenario within an optometry or general
ophthalmology practice in the USA could be that a technician or assistant is
taking measurements with the i.Profiler
plus
in the pre-exam room as a starting
point for the subjective refraction.
Within a networked practice the auto-retractor values may be transferred
automatically to an electronic phoropter head while the raw data would be
transferred automatically to a review software running on a PC in the exam
room. Following the subjective refraction and other eye examinations the
OD/MD would review the wavefront data to discuss the planned or
recommended application with the patient. Once a decision is made, either
the technician would execute an order via the practice PMS system or straight
through the review software (e.g. i.Scription lens order) or the doctor would
save and print a report for manual ordering.
